CONTAINER AND SEALING MEANS THEREFOR.

Application filed March 3, 1927. Serial No. 172,377.

My invention relates to containers which are provided with bungs in theform of threaded plugs which are received withln the threaded interiorsof bushings that are as sembled with wall portions of the containers,

the invention finding particular use in connectionwith barrels in whichoil or other liquid is packaged for shipment.

The invention has for its object the provision of means for obstructingundetectable access to and removal of the plugs. To this end I place ahood upon the outer end of the plug, which usually has a tool engagingformation and a circumscribing flange upon its outer end, access towhich being obstructed by the hood which surrounds and encloses saidflange and tool engaging formation.

The invention will be more fully explained in connection with theaccompanying drawing in which Fig. 1 is a view illustrating thepreferred embodiment of the invention, the bushing and a portion of thecontainer wall being shown in section while the plug and hoodare shownin elevation with a portion of the hood broken away; Fig. 2 is asectional view of the plug and its hood on line 22 of Fig. 3; Fig. 3 isa sectional view on a larger scale on line 3-3 of Fig. 2; and Fig. 4 isa side view of the hood before it is applied. 1

The container, such as a barrel, has one wall 1 thereof formed with adepending rim 2 which surrounds a circular hole formed through thiswall. An interiorly threaded bushing 3 is snugly received within thishole and is closely surrounded by said rim, this bushing being shownwith an outwardly curled inner edge portion 1 which grips the inner edgeof said rim 2 and a circumscribing flan e 5 which is tightly seated uponthe wall 1, t iis flange desirably lapping this wall on the exterior of'the container. The closure plug 6 is screwed within the bushing 3 and isformed with a circumscribing flange 7 which laps the flange 5 and wall1, an annular sealing-gasket 8 being desirably interposed between theflanges to render the joint between the plu and bushing fluid-tight.,The flange 7 is esirably conically tapered toward the wall 1. The outerend of the plug is formed with two tool engagingformations, one intheform of an enlargement 9 which is of hexagonal or polygonal exteriorcontour, and the other in the form of a recess 10 extending through [theenlargement 9 and into the body of the plug, this recess being of squareor other contour to receive a wrench having a plug formation snuglyreceivable within and corresponding in shape to said recess.

The sealing device or uard of my invention is in the form of a ood 11whose skirt portion 12 is inwardly turned to snugly embrace the taperingflange 7 .and desirably terminates at the gasket 8 to prevent the flange7 from being reached by a dislodging tool. The crown of the hood coversthe outer end of the plug and its tool engaging formations 9 and 10.

The material of which the hood is made '0 is desirably very thin sheetmetal such as tin which will readily tear or become ruptured if b anyattempt is made to loosen the plug as by means of wrenches applied tothe plug flange 7 or the plug enlargement 9. The plug flange 7 is formedwith angular portions 7 adjacent thehood to aid in tearing the hood whena dislodging tool is applied to the flange. The taper of the flangemakes it difiicult to apply a dislodging tool thereto. so

Changes may be made without departing from the invention.

Having thus described my invention, I claim:

1. The combination with acontainer 35 formed with a hole through a wallthereof and carrying screw threads surrounding said hole; of a closureplug screwed into said threads and having a flange at its outer portion;and a hood carried by the plug and so embracing said flange, said flangebeing formed with angular vportions adjacent said hood to aid in tearingthe hood when a dislodging tool is applied to said flange.

2. The combination with a container formed with a hole through a wallthereof and carrying screw threads surrounding said hole; of a closureplug screwed into said threads and having a flange at its outer portionwhich tapers toward said container wall; and a hood carried by the plugand embracing said flange, said flange being formed with angularportions adjacent said tion which tapers; and a hood carried by the hoodto aid in tearing the hood when a displug and einbracingsaid flange,said flange 10 lodging tool is applied to said flange; being formed withangular portions adjacent 3. The combination with a container said hoodto aid in tearing the hoodwhen a 5 formed with ahoie through a wallthereof disiodging tool is'applied to said flange.

and carrying screw threads surrounding said In Witness whereof, Ihereunto subscribe hole; of a closure plug screwed into said my naine.
